农林废弃物在防风固沙中的应用研究

Study on the Application of Agricultural and Forestry Wastes in Windbreak and Sand Fixation

土地沙化是全球面临的主要生态问题之一,严重影响社会生产生活。寻求经济合理、方便高效、生态环保的防风固沙材料对沙化治理有着至关重要的作用。农林废弃物数量巨大、可再生,其再利用对降低垃圾处理压力、实现资源高效化利用有积极意义。同时,农林废弃物能改善土壤理化性质,对沙化治理有一定可行性。论述了农林废弃物在防风固沙研究中的主要应用形式及特点,包括工程固沙、化学固沙及生物固沙方面的相关研究成果,并对今后进一步研究提出了建议,以期为农林废弃物在防风固沙领域的应用研究提供参考。

Land desertification is one of the main ecological problems in the world today, which seriously affects social production and life. It is of great significance to seek economical, reasonable, convenient, efficient and ecological sand fixation materials for desertification control. The amount of agricultural and forestry waste is huge and renewable. Its reuse is of positive significance to reduce the pressure of waste disposal and realize the efficient utilization of resources. In addition, agricultural and forestry wastes can improve the physical and chemical properties of soil, which has certain feasibility to prevent desertification. The main application forms and characteristics of agricultural and forestry wastes in windbreak and sand fixation were discussed, the related research results of engineering sand fixation, chemical sand fixation and biological sand fixation were introduced,and suggestions for further research were put forward, in order to provide reference for the application research of agricultural and forestry wastes in windbreak and sand fixation.
